Carnosol

Carnosol is a phenol that has been found in rosemary (R. officinalis) and has diverse biological activities. It decreases nitric oxide (NO) production in mouse peritoneal exudate macrophages when used at concentrations ranging from 6 to 25 µM. Carnosol scavenges peroxyl and hydroxyl radicals and inhibits lipid peroxidation in cell-free assays. It inhibits 5-lipoxygenase (5-LO, IC50 = 0.1 µM for the recombinant human enzyme) and the synthesis of leukotrienes in human polymorphonuclear leukocytes (PMNs, IC50 = 7 µM). In vivo, carnosol (200 mg/kg) reduces mammary DNA adduct formation and tumorigenesis in a rat model of DMBA-induced mammary tumorigenesis.Formal Name: 1,3,4,9,10,10aS-hexahydro-5,6-dihydroxy-1,1-dimethyl-7-isopropyl-2H-9S,4aR-(epoxymethano)phenanthren-12-one.
